HPS Performance Products 5/16" Blue 4-Ply Reinforced Silicone Coolant Tube Coupler Hose 3 Feet
$33.32

If you're diving into some serious projects, whether it’s a custom turbo setup or just needing a solid hose for your radiator, the HPS 5/16" (8.0mm) x 3 Feet Long High Temp 4-ply Reinforced Blue Silicone Tube Coupler Hose is worth a look. This isn’t just any hose; it’s built to last and handle some serious heat, meeting the SAEJ20 standards that you want in a heavy-duty connection.

With a temperature range that spans from -65°F to a scorching 350°F (that’s about 177°C for those who like metrics), this hose is tough enough for marine and industrial applications. The 4-ply construction means it's reinforced to take on high pressure without flinching, so you can trust it for those demanding jobs. The inside diameter is 5/16" (or 8.0mm), while the outside measures 0.71" (18mm)—perfect for snug fits without compromising flow.

One thing I really appreciate is how UV and ozone resistant this silicone hose is. It’s built to withstand the elements, which is a must if you’re out on the water or working in harsh environments. Just a heads up, though: it doesn’t play nice with fuel or oil, so keep that in mind when planning your setup.

So, whether you’re fabricating some custom intercooler piping or just need a reliable hose for your DIY intake, this HPS silicone tube coupler is a solid choice. It’s not just about specs; it’s about having a part you can trust when the heat is on.
